Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

With reference to fig. 1, an embodiment of the utility model provides a crystallizer arc adjusting wrench, which is used for adjusting the arc of a crystallizer when the crystallizer is newly on line, arc adjusting nuts are arranged on two sides of the crystallizer, and the arc adjusting can be realized by rotating the arc adjusting nuts through the wrench. The arc adjusting wrench includes a main body 100, a fixing member 200, and at least one striking arm 300.

Wherein the main body 100 is a basic member of a wrench for providing a mounting base for other wrench members, the fixing member 200 and at least one striking arm 300 are provided on the main body 100. The main body 100 is provided with an arc adjusting opening 110 for buckling the arc adjusting nut, and when the arc adjusting nut is buckled in the arc adjusting opening 110, the main body 100 can rotate to drive the arc adjusting nut to rotate. When the arc of the mold is adjusted, an operator uses a tool such as a hammer to strike the striking arm 300, so that the striking arm 300 rotates, and the striking arm 300 drives the main body 100 to rotate. The fixing member 200 is used for fixing the main body 100 on the arc adjusting nut, so that the wrench can be prevented from falling off.

According to the crystallizer arc adjusting spanner provided by the embodiment of the utility model, the fixing piece 200 is arranged on the main body 100, and the fixing piece 200 can fixedly arrange the main body 100 on the arc adjusting nut of the crystallizer, so that when the arc of the crystallizer is adjusted, the fixing piece 200 is firstly used for fixedly arranging the main body 100 on the arc adjusting nut, then the striking arm 300 is knocked by using a tool, so that the spanner drives the arc adjusting nut to rotate for arc adjustment, and as the main body 100 of the spanner is already fixed on the arc adjusting nut, the spanner can be prevented from falling, a long rod is not required to be used for supporting the spanner manually, one person is realized for arc adjustment, the labor is saved, and the production efficiency is improved.

Further, the fixing piece 200 includes a tightening portion 220, the tightening portion 220 is fixedly disposed in the main body in a penetrating manner, and the tightening portion 220 can tightly tighten the arc adjusting nut, so that the main body 100 is fixed on the arc adjusting nut, and the fixing piece 200 can be disposed at any position of the main body 100.

The fixing piece 200 further comprises an operation portion 210, wherein the operation portion 210 is disposed at one end of the abutting portion 220 away from the arc adjusting nut, so that an operator can operate the abutting portion 220 through the operation portion 210 to facilitate the operator. Specifically, the operation portion 210 and the abutting portion 220 may be vertically disposed.

After the arc adjustment, the wrench needs to be removed from the arc adjustment nut, so the fixing member 200 needs to be detachably disposed on the main body 100, such as a screw connection. Specifically, the fixing member 200 may be a locking bolt, the head of which is configured as the operation portion 210, the shaft of which is configured as the abutment portion 220, and the tightening bolt may employ M10 x 30mm.
